To all tf1/omit may concern.'

Be it known that ITMILTON E. KREIDLER, a citizen of the United States,residing at Bethlehem, in the county of Northampton and. Sta-te oifPennsylvania', have invented new and useful Improvements in Shoe Lasts,oi" which the following is a specification.

This invention relates to improvements in shoe lasts and the principalobject of the invention to provide means for adjusting the last withinthe shoe so as to hold the shoeythe upper oi' the shoe.

The invention also consists in certain other 'features oil constructionand in the combination and arrangement ot the several parts, to behereinafter fully described, illustrated in the aeeoimoanying drawingsand specifically pointed ont in the appended claim.

ln describing niv invention in detail, ref-1 crence will be had to theaccompanying drawings wherein like characters denote like orcorresponding parts throughout the several views. and in which Figure 1is an elevation. of the last constructed in vaccordance with myinvention and showingthe same expanded.

Figure 2 is a longitudinal section showing the last contracted.

Figure 3 is a plan view.

Figure t is a horizontal section.

Figure 5 is a section on line 5-5 of Fig ure 2.

Figure 6 is a like section but showing the parts in a differentposition.

Figure 7 is a section. on line 7-7 of Figure l.

Figure 8 is a longitudinal section. through the gear supportingbrackets.

Figure 9 is a sectional view through one of the worm gears.

`Figure 10 is a view of the wrench for use with the device.

In these views 1 indicates the heel part of the last and 2 the toe part.overlap each other.. as shown, and the overlapping part of the toeportion is provided with a groove 3 for receiving the wrench engagingend 4 of the rotatable shaft 5 carried by the heel part. Theheel part isThese parts provided with-an angle bracket 6 which carries said shaft.The vertical part of this braclret carries a screw-threaded shaft 7 andthe two shafts are lgeared together'by the bevel gears 8. A'plate 9 issecured to the lower vertical `face of the'toe part 2 and this plate isprovided with a screw threaded socket 1() for receiving 4the shaft 7.1The bracket G also carries a guiding part 11 which engages an opening inthe plate 9 :for guiding the two partsl of the lastin their movements. A

ltwill thus be seenithat `when the shaft 5 is rotated, by. means of thewrench 12 shown in Figure i0-, the screw threaded shaft 'T will also be`rotated and-the engagement of its threads with the screw threaded socket10 will cause the two parts of the last to be moved relative to eachother and thus the last may be expanded or contracted in the shoe. Theslot 3 in the overlapping part of the portion 2 will permit thisoverlapping part to pass by the end l of the shaft so that the two partsof the last may be brought together'. This slot is large enough topermit the entrance of the wrench.

A bow-shaped platerlB is carried by the toe part 2 ot the last and thisplate embraces the upper portion thereof adjacent the toe. This plate isverticallvmovable so `that it may be used for stretching vthe upper ofthe shoe and in order to niove this plate l provide the same with afpair of screw threaded studs 14 which project downwardly from its innerwall. These studs engage the screw threaded hubs 15 of the gear wheels16 and these gear wheels are carried by the U- shaped end of a plate 17,which is secured in.

a recess 18 formed in the part 2 of the last. The looped end ofthe plateis provided with the openings 19 for receiving the hubs of' the gears sothat the said gears. are rotatably held between the two parts of theplate with the screw threaded studs passing, through said hubs asclearly shown in Figures 2, 5 and 6.

The gears 16 are engaged by the last gear ot a. train of gears 20,carriedby thefplate and this train of gea-ring is set in motion by thewrench 12 engaged by the square shank 21 of the shaft 22, rotatablymounted in the plate and carrying one of the gears. I prefer to oifsetthe inner end of the plate and to' place the first two gears on thisoffset portion so that these two gears are above the plane of the othergears with the second and third gears carried by the saine shaft. Bythis ineans the Shank ,21 is placed nearerthe top of the last so that itmay be easily engaged with the wrench.

It will be'seen that when the shaft 22 is rotated by the wrench itsmotion will be i1nparted to the two gears 16 and thus the studs lll willbe rnoved vertically to raiseor lower the carved plate 13.

l n'lay secure button-shaped members 23 t0 the Quteriace of said platewherever desired to stretch :the shoe at these points in order to formrecesses n the shoe to receive `the cornsl or other growths on the4foot.

By my invention the last after being placed inthe shoe may 'be expandedto stretch the Vsame and to provide recesses to receive corne and thelike. Y By the use of my device the shoes may be made to last longer `aswrinkles and creases can be stretched out of the shoe and the shoe maybe made to assume its original shape after becoming wet.

It is thought from the foregoing description that theadvantages andnovel features `01;' my'invention will he readily apparent.

I desire it to be understood that I may niake changes in theconstruction and in the combinationand arrangement of the several parts,provided that such changes fall within the scope of the appended claim.3

What I claim is v A shoe last having arecess therein, a plate located inthe recess and having its toe end of U-shape, a. toothed wheel having ascrew threaded central opening located between the 3: limbs ol theU-shaped part of the plate, a

n testimony whereof I aix my signature.
